Richmond officials have rejected a proposal by Lamar Advertising to remove a billboard on the Shockoe Hill African Burying Ground in exchange for help finding locations for additional advertising in the city. The billboard, which is visible to motorists on Interstate 64, has been the source of ongoing controversy because of its location atop the grave site. The site is estimated to be the largest enslaved burial ground in the country. The company owns an easement on the northeast portion of the property, where the 14-foot-tall billboard has stood for about 20 years.
